以五水四氯化锡和氟化钠为主要原材料，通过溶剂热法，制备F掺杂纳米SnO2粉体，利用X射线衍射(XRD)、透射电镜(TEM)、电子显微镜(EDS)对所制备样品进行了表征，以及通过对罗丹明B、甲基橙、亚甲基蓝等模拟废水降解实验来评估所制备的F掺杂SnO2粉体的光催化性能研究。结果表明：当F掺杂浓度为n(F)/n(Sn)=1∶18、添加3 g聚乙二醇、反应时间为5 h、反应温度为200℃、投加量为0.05 g，采用可见光对罗丹明B的降解效果最好，降解率为98.33%。
Abstract：Using stannic chloride pentahydrate and sodium fluoride as the main raw materials, F doped nano SnO2 powder was prepared by solvothermal method. The prepared samples were characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM) and electron microscopy(EDS). The photocatalytic performance of the prepared F-doped SnO2 powders was evaluated by the degradation experiments of simulated wastewater, such as Rh B, methyl orange and methylene blue. The results show that when the F doping concentration is n(F)/n(Sn)=1 ∶ 18, 3 g polyethylene glycol is added, the reaction time is 5h, the reaction temperature is 200 ℃, and the dosage is 0.05 g, the best degradation effect of Rh B is achieved by using visible light, and the degradation rate is 98.33%.
